I was invited to give a plenary address at the SISPAD conference in September 2021. For anyone not familiar with SISPAD it is a premiere TCAD conference. This year for the first time SISPAD wanted to address cost and my talk was “Cost Simulations to Enable PPAC Aware Technology Development”.
For many years the standard in technology… Read More
Samsung and TSMC have both made recent disclosures about their 5nm process and I though it would be a good time to look at what we know about them and compare the two processes.
A lot of what has been announced about 5nm is in comparison to 7nm so we will first review 7nm.
Figure 1 compares Samsung’s 7LPP process to TSMC’s 7FF and 7FFP… Read More
The semiconductor foundry business has gone through a dynamic transformation over the last 30 years. In the beginning the foundries were several process nodes behind the IDMs with little hope of catching up. Today the foundries are leading the process development race at 10nm – 7nm, and will continue to do so, absolutely.… Read More
There is a report in the Seoul Economic Daily that Samsung has completed development of their 7nm process using EUV and that production will begin in June. What is claimed in the report is:
- The process is installed in the Hwaseong S3 Fab
- Samsung has more than 10 EUV systems installed
- Production starts in June with Qualcomm, Xilinx,

The 63rd annual IEDM (International Electron Devices Meeting) will be held December 2nd through 6th in San Francisco. In my opinion IEDM is one of, if not the premier conference on leading edge semiconductor technology. I will be attending the conference again this year and providing coverage for SemiWiki. As a member of the press… Read More
For many year 2D NAND drove lithography for the semiconductor industry with the smallest printed dimensions and yearly shrinks. As 2D NAND shrunk down to the mid-teens nodes, 16nm, 15nm and even 14nm, the cells became so small that there were only a few electrons in each cell and cross-talk issues made further shrinks very difficult… Read More
At the ISS Conference in January, An Steegen EVP of Semiconductor Technology & Systems at imec gave a talk entitled “Patterning Options for Advanced Technology Nodes”. I was present for her talk and had the opportunity to have a follow up interview with An.… Read More
The use of simulation is well established in the semiconductor industry. Virtually all circuit designs are run through a Spice simulation, layouts are analyzed for timing issues and even process development employs process simulation tools. What I believe is less widely used but just as useful is cost modeling.
The semiconductor… Read More
In the third installment of this series we discussed the status of DRAM scaling and Moore’s law. In this installment we will tackle logic. The focus will be on foundry logic.
Logic technology challenges
In the second installment of this series we discussed constant electric field scaling. As we mentioned in that installment at … Read More
I recently published an article on Semiwiki “Is SOI Really Less Expensive”. That article was the result of months of careful research and analysis. I looked at planar FDSOI versus bulk planar, bulk FinFETs and FinFETs on SOI at three different nodes. I took a consistent set of assumptions with respect to the fab used to run the processes,… Read More
